I've decided to go to the way back machines, and I was able to download Deflemask version 7 (the first and only version that had the ability to export GB ROM images at a custom refresh rate with no problem) and then as I went up to version 8 and up, I can no longer export GB ROMs at a custom refresh rate. I now get the "ROM export error" message.The question is, why did you disable it? however it still works in VGM export, but I am unable to test VGM playback because at this time, there are no VGM players for Mac OS X that support VGM version 1.61, and VGMplay has no wine compatibility.Anyways, here's a GB ROM that i've exported from Deflemask 7 to show you that it actually works.

Anyways, in the Commodore 64 Duty Cycle editor, setting the Duty Cycle to a negative number (ex. going from 50 to 38) will instead cause it to go in the opposite direction. (ex. goes from 50 to 62)If you could tweak this that'd be great.

PS: The Duty Cycle editor also can only move to Duty Cycles 12 units away. Is this a hardware thing, or is it something you can extend?

I was expecting some compatibility issues with hes playback. The only player that (sort-of) plays the files properly is NEZplay.Audio overload doesn't play them at all.Fox audio player plays them vary slowly.PCM samples don't work in exported files.
